    Abstract

    In the present study the resistance of beams treated by ThermoWood[...] process was studied in ground contact and the results given are based on a "modified" EN 252 test. After six years' exposure clear differences were found between untreated Scots pine and Norway spruce beams and treated ones. In all cases thermal modification improved the performance. Thermally modified pine heartwood showed the best performance, where only partial decay was found in the outer part of glue-laminated beams s. Decay was more accelerated in Scots pine sapwood, and especially within untreated pine sapwood posts, severe decay was found.
